CURB AND HOLDFAST FOR GAS-PURIFIERS.

Specification of Letters Patent.

Patented Dec. 9,1913.

To all whom it may concern:

Be it known that 1, Banner F. LLOYD, a

' citizen of the United States of America, re-

siding at Detroit, in the count-y of lVayne and State of Michigan, haveinvented certain new and useful Improvements in Curbs and Holdfasts forGas-Purifiers, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to clamping means for securing a closure on gaspurifier tanks, holders, etc., and more especially to an arrangementthereof for holding the closure on the curb of a concrete tank, theparts being so disposed as to permit ready removal of the closure whilethey are also arranged so that unskilled labor may readily assemble thestructure.

The invention relates to matters hereinafter set forth and pointed outin the claims.

In the drawings, Figure 1 is a view in section of the curb of a divisionwall between two tanks provided with closures that are retained byclamping means that embody features of the invention; Fig. 2 is asimilar view showing an outer wall of a tank with a slight modificationof the clamping means; and Fig. 3 is a plan view in detail of a part ofa clamping bolt taken on or about line IIIIII of Fig. 1.

As herein shown in preferred form, a curb 1 of a tank wall or of thedivision wall between two embedded tanks is formed of concrete or likecementitious material in which Lbeams 2 or sills are embedded with theirupper flanges flush with the top of the curb. Angle plates 3 are securedto the webs of these I-beams or sills at regular intervals and areapertured in their horizontal flanges 4 to allow the passage of anchorrods 5. The latter are secured against longitudinal displacement by dragplates 6 near their ends or otherwise by reinforcing bars 7 around whichthe ends 8 of the rods (Fig. 2) are hooked. The upper end portions ofthe anchor rods are formed into or provided with transversely slottedheads 9 that rest upon the flanges 1 and are of such dimensions thatthey can only be placed adjacent the upper flanges of the beams 2 withthe head slots transverse to the latter.

Bolts 10 are appropriately pivoted in the members 9 so as to passthrough openings in beyond the margins of the tank closures. Suitablenuts 12 force the clamps downwardly toward the curb 2.

As herein shown the clamping plates 11 are bolted to longitudinal beams13 and transverse beams IA of a closure having a deck plate 15 ofsuitable material with a side member 16 as indicated in Fig. 1. Angleplates 17 are used to connect the edge of the deck with the side memberwhile an exterior angle 18 and a retaining strip 19 serve to hold agasket 20 in position to rest on the channels 2 or curb.

If preferred, the plate 16 may be replaced by a channel bar as indicatedat 21, in which instance a gasket 22 that rests on the curb or'curbbeams, is suitably secured by any preferred means, as indicated, to abeam 23 whose oppositely extending upper flanges 24 support the deck andthe lower flange of the member 21.

By either construction anchorage is obtained that effectively holds theclosure to the curb and is so arranged that any unforeseen movement inthe cement or mass of the curb does not throw the anchor members out ofline with the side of the closure. Furthermore the disposition of theparts is such that it is impossible to embed the anchor rods unless theyare turned in proper position to allow the swinging away of the upperportions from the closure when unclamping the latter. As indicated inFig. 1 the construction enables the use of a comparatively narrow curbon the division wall between two tanks as the parts lie within acomparatively narrow space.

Obviously, changes in the details of construction may be made withoutdeparting from the spirit of my invention and I do not care to limitmyself to any particular form or arrangement of parts.

hat I claim is 1. The combination with the curb of a tank or the likeand a closure therefor having a yielding gasket between it and the curb,of sill members embedded in the curb, anchor rods in the curb passingthrough guide openings in projections of the sill members, anchor boltspivoted to the rods and clamping plates on the closure engaged by thebolts.

2. The combination with the curb of a tank or holder of cementitiousmaterial, and a closure, of means for forcing the closure to seatconsisting of sill beams embedded in the curb, lateral extensionsthereon, anchor rods in the curb passing through apertures in theextensions, bolts pivoted to the rods and clamping plates on the closureengaged by the bolts.

'3. The combination With the-curb of atank or holder of oeinentitiousmaterial, a closure therefor, and a gasket sealing the joint between theclosure and sill, of sill 1o beams embedded in the curb, lateralextensions thereon, anchor rods in the curb passing through apertures inthe extensions, bolts pivoted to the rods and clamping plates on theclosure engaged by the bolts.

In testimony whereof I affix my signature in presence of tWo Witnesses.
